At Berry Campbell Gallery, “Louisa Chase: The Eighties” is less a rediscovery than an emphatic reassertion of a leading painter who resisted easy categorization within the shifting narratives of the Neo-Expressionist and New Image movements in New York. Featured in this, the largest exhibition of the artist’s work in New York City in over 25 years, are works that span the decade between mid-1970s and the mid-1980s, Chase, who died in 2016, emerges as a more complex and pivotal artist than she is usually considered.
